All kinds of loads will pass to it. So the performance of frame structure affects whether the automobile design is successful or not. As a part of the truck, the frame supports all kinds of complicated loads coming from the road and freight. And many assembly of the truck are built in the frame. So the intensity and the strong of the frame play a very important role in the design of trucks. A model of the frame is established by using Pro/E in this paper. The static intensity of the frame is analyzed in the situation of bending, torsion, braking and swerve by ANSYS. The result indicates that the stress of the frame is less than the utmost intension. And the frame is satisfied with the design. ...
